- extends above the cap 58, thus holding it in y overlap the ends of the ridge caps 32 and the transverse cap 40 between them, andv through the ridge beam 16. The ruiming board 50 is supported by the saddle blocks 49. 1When assembled as above described. the caps 40 form a water tight joint and at the same time the edges 42 of the caps, while firmly holding the metal sheets against the board sheathing, do notinterfere with the freedom of movement of said. sheets in the plane of the roof. p. A

The lower or outer edges of the root sheets 26 are simply doubled under .as indi cated by the reference numeral 52. Clips 53 are fastened by means of bolts 54 tothe fascia 19, and each clip has a prong which reaches up over the edge 52 of the roof sheet 26. Other similar clips 55 each have a prong that reaches up overthe outer end of the transverse cap 40.

At the end of thecar', a strip is laid acrossabove the end 'wall 56. This strip 57 corresponds to the blocks 48 already de# scribed. A, special cap 58 having the cross section shown in Fig. 7 has a flange 60 that extends over the upturned edge of the adjacent rootl sheet 26 and another flange 59 that extends over the end ofthe car. Clips t 61 are fastened by bolts 62 to the end wall oi the car and each clip has a prong which place.

It is to be observedthat the parts arevso proportionedand assembled that the upturned edges 27-28 of the roof sheets 26 are given a certain amount of clearance (see Figs. 3 and 6). Thus, it will be seen that each plate 26 is pivotallyattached to the board roof 20 by means of the interlocking Y'/bosses 23 and 30, and that it is possible to rotate each plate 26 within narrow limits about the bolt 38, as an axis. It accordingly follows that if the car roof is strained from any cause, whether this be due to 'sagging at the center or to diagonal 'stresses7 or any other cause, suchdistortion'of the board roof 20 will not be communicated to the metal roof sheets 26. Thus, it will be seen that I havey provided a sheet metal cai' rootl which will not become broken and bent been done without affording any access for yrain water. The caps 32 and 40 it over the adjacent edges of the roof sheets so as to practically exclude rain water. Then if any water should drive under the edges of these caps, it will be caught by the hooked edges 2e' of the roof sheets 26 and no water will succeed in getting between the edges ot adjacent roof sheets 26.

It will be observed that the blocks 37 with theirs'oclets 30 engaging the bosses 30 give a very secure pivotal support for the roof sheets 26. The ruiming board is supported on the blocks 4S and 49, which in turn rest upon the beardl root' 20 between the roof sheets 26. Thus, it will be seen vthat thel weight of the ruiming board is not transmitted through the roof sheets 26, thus leaving them free to be rotated around their pivotal bosses 30. The clips -and at the edges of the roofv simply keep the edges down in place,-but do not prevent a slight dlisplacement of the rootl sheets under the c ips.

`l would have it understood that I do not desire to limit myself to the precise construction and. arrangement of parts shown in the drawings and herein described, as'variousalterations or modifications may be made without departing from the spirit of my invention as/detined in the appended claims.
